The Functional Advantage of AYG Long Stroke Pumping Unit

The power assembly of this machine uses worldwide leading commutation technology, with advanced braking devices. First, the flexible braking system is agile and accurate when the machine is stopped during operation; second, power loss braking is stable and reliable; third, automatic brake system will work when unblocking or out of control of external traction force. At the same time, the stroke limit protection device is installed at top dead center and lower dead center of the guide rail to ensure the safety and reliability of the machine during.

The machine is with direct gravity balance counterweight method, when the sucker rod moves up and down, the balanced weight makes the power source approach balanced driving, which effectively reduces the traction force and effectively reduces the power consumption during the operation of the pumping unit. Compared with the beam pumping unit, it can save more than 50% energy. And the counterweight box contains detachable counterweight blocks, which is convenient for user to adjust the weight of counterweight box according to underground working conditions. And the machine has one-sided suspension performance. Under the condition of weightlessness of external traction, the internal counterweight box can be lifted down without using any external lifting tools.

The electric control cabinet is installed at the bottom and behind of the equipment. The equipment can be controlled/operated both inside and outside of the cabinet. Its variable frequency speed control function can meet the needs of both low and high speed long stroke motion, and has jog operation function.

The professional design of automation control system is stable, safe and reliable. It meets the requirements of convenient operation, reliable performance, stable structure, low repair rate and high working efficiency.
